Scour around Cross-Threaded Piers in Regular Waves

This paper conducted the experiment on the formation scour around cross-threaded piers subjected to regular waves. The factor formations of scour had been identified by extensive research of previous paper that related to the project. From the gap of previous research, the project constructed physical model of the protected and unprotected pile. This study used cross-threaded pile as a flow-altering countermeasure mechanism to obtain results on average of scour reduction compared unprotected pier with variation of cable diameter and thread angle. The flow pattern around the pile was observed and the effect of wave period on the formation of scour was analysed. However, with the time constraint and the availability of the instrument, only a few test series and wave condition studied in this paper
